Abstract
Novel dyestuffs containing amino or imino groups and their preparation are provided.
These dyestuffs have the general formula ##STR1## wherein R is --N(R3)CH2 --Z or --N═CH--Z, X is N or CR6 where R6 is a hydrogen atom or an optionally substituted alkyl or aryl group, Y is S.sup.⊕, O.sup.⊕, N or N.sup.⊕ R7 where R7 is a hydrogen atom or an optionally substituted alkyl or aryl group, R1, R1 and R2 each represent a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, or R1 and R2 together with the nitrogen atom complete a heterocyclic ring, or one of R1 and R2 can be hydrogen and the other of R1 and R2 can be aryl, Z is a group which comprises both an activating group which contains at least one double bond system and also a ballasting group and R4 and R5 each represent optional substituents or form an annelated benzene ring. The new dyestuffs are useful in the photographic field especially in the photographic dye diffusion transfer process for the production of photographic images.
